BEVELING-VIACHINE.

SPECIFICATION forming part of Letters Patent No. 598,257, dated February1, 1898.

Application filed August 1 8 94.

To all whom it may concern:

Be it known that I, VERNON ROYLE, of

. Paterson, in the county of Passaic and State of New Jersey, haveinvented a new and useful Improvement in Beveling-Machines, of which thefollowing is a specification.

My invention relates to an improvement in beveling-machines, and moreparticularly to that class of bevelers which are employed in connectionwith half-tone plates, which leave a proving-bearer surrounding thebeveled j edge of the engraving, which bearer can be removed at will byhand or by the aid of a pair of pliers, according to the depth of thecut. In plates of this character their thinness renders them peculiarlyliable to bow up under the cutter, and the danger of inj uring theengraved surface attendant upon using ordinary forms of clamps hasrendered it difficult to produce a satisfactory beveling machine.

The object of the present invention is to provide means for overcomingthe difficulties Fig. '3 is a top plan view, the table being re-` moved.Fig. 4 is a top plan view of the table in detail. Fig. 5 is an end viewof the table, showing a portion of the carriage in section. Fig. 6 is apartial'view, in front edge elevation, of the table. Fig. 7 is a topplan view of the clamp and portion of the table. Fig. S is a view invertical transverse section through the clamp, its operating-shaft, anda portion of the table.

Figs. 15 and 16 are partial plan and sectional 'views of one of theplates, showing the bev eled grooves cut therein. Fig. 17 is a topplanview of the machine with certain of the parts broken away to showmore clearly other parts beneath them; and Fig. 18 is an enlarged viewin detail, showing a partial vertical section through the table alongthe central portion of the sliding plate G.

The pedestal on which the working parts of the machine are mounted isdenoted by A and is made heavy and rigid to prevent torsional strain andother derangements incidental to uneven and settling floors. It isprovided with a door a, opening into its hollow interior, which latteris employed as a store-room for tools. i

The table for supporting the parts to be opn erated upon is denoted by Band is supported 'upon a carriage B, mounted upon the said whichintermeshes with a bevelgear c2 on a screw-threaded shaft c3, whichengages a nut c4, fixed to travel with the carriage.

,The table B is provided on its under side with an elongated recess b2for the reception of the head d of an arm projecting froma rock-shaft D,journaled in the carriage, and provided with an operating-arm d',projecting from the shaft at an angle to the arm cZ and under thecontrol of a thumb-screw d2 to rock the shaft and thereby slide thetable transversely withrespect to the travel oi' the carriage. A springd3 is employed to hold the arm d against the end of the adj usting-screwcl2, and the tension of the spring da is intended to be sufficient torock the shaft D and slide the table in one direction-wiz., thedirection opposite that in which it is forced by the turning down of thescrew d2.

.The table B has an additional adjustment vertically with respect to thecarriage B for IOO the purpose of moving the work toward or away fromthe cutter, and hence increasing or decreasing the depth of the beveledgroove. This adjustment is effected by means of a wedge-shaped bar E,which rests and slides upon a beveled seat e at the rear of thecarriage, with its upper horizontal edge engaged with the rear edge ofthe table. The wedgeshaped bar E is held in position by means of screwse, which pass through elongated slots e2 in the bar and enter the rearof the carriage. The barE is moved longitudinally with the greatestaccuracy by means of a thumbnut e3, which engages a fine screw e4, fixedin the end of the sliding bar E. The nut e3 is held againstlongitudinalmovement by means of a collar on its hub which loosely engages a supporte5, fixed relatively to the bar E, so that the nut e3 may rotate freelyin either direction, and hence while held against longitudinal movementitself force the screwe4, and hence the bar E, Ain one direction or theother, as may be desired.

The table B4 is secured to the carriage by means of a single bolt F,which extends through an enlarged opening f in the carriage and thenceinto the under side of the table, the bolt having inserted between itshead and the carriage yielding washers f, so as to permit the swayingmovement of the bolt F in the carriage a distance sufficientto permitthe transverse adjustment of the table with respect to the carriage anda vertical yielding movement sufficient to permit the vertical movementof the table hereinabove referred to. rlhere is also preferablyametallic washer f2 located between the head of the plate and theyielding washer or washers f to give the bolt-headr a more extendedbearing on the yielding washers.

Lost motion due to wear between the head CZ of the double operating-armand the walls `of the elongated recess b2, in which it engages,

Ymay be taken' up by means of a sliding plate G, located in the underside of the table and under the control of an adj Listing-screw g tomove it longitudinally and a clamping-screw g to hold it fast to thetable, the end of the plate Gr being located at the wall of the recessin the under side of the table, so that the recess may be narrowedslightly at the point where the head CZ enters it.

The plate to be operated upon is clamped yto the table by means of avertically-movable clamp H, mounted at its ends in sliding adjustment instandards Zz, uprising from the table B,and provided with a pair ofrackbars Zt which mesh with inions h2 on a ro' tary shaft h3, mounted insaid uprising standard 7L and operated by means of a worm i on anoperating-shaft I, provided with a handwheel fi', the said worm 'L'engaging a wormwheel h4 on the shaft h3. The lower or operating face ofthe clamp is preferably made broad to give it an extended bearing uponthe plate to be held.

For placing the work in the proper position on the table B With respectto the cutter, to

be hereinafter described, I provide two gages, one of them, K, securedto the supportingframe and the other, L, mounted on the table. The gageK is fixed in the present instance .b f set-screws 7o toa swinging frameZr )ivotally secured ecceutrically to the ends of a rock shaft or bar7a2, which latter has adjustably fixed thereon a sleeve k3, providedwith a collar 104 for turning the shaft k2 and thereby throwing the gageK a greater or lesser distance over the rear edge of the plate to beoperated upon. The sleeve 7a3, which carries the shaft 7a2, is mountedin the upper end of a supporting-standard 705, which standard is splitat its upper end and provided with a set-screw k6 for the purpose ofclamping the To relieve the concussion when of which is in position tobe engaged by a lug 7a, fixed to rock with the swinging frame Zr' `andso located that the said lugk1G will strike the spring k7 just beforethe gage reaches the limit of itsforward swing.

The gage L is fastened by screws Z to a swinging support Z, fixed to therock-shaft Z2, provided with an actuating-spring Z3, ,the tension ofwhich tends to keep the gage depressed, With its sharp edge Z4 in thebottom of the beveled groove. The gage Z4 may be lifted from itsposition in the groove by means of an operating-handle Zw, fixed toeither the gage-supporting piece Z/ or to the shaft Z. The rock-shaft Z2is mounted in the supporting-piece Z5, removably-secured to the face ofthe adjustable supporting-plate Z6, provided with a dovetailed tongue ZTand a tapered tongue ZS, adapted to fit in corresponding groovesextending lengthwise of the table BC The plate ZG is clamped in thedesired adjustment longitudinally along the table B by means of athumb-nut Z9, which enters a screw secured to the dovetailed tongue Z7,or, as I prefer, the tongue Z7 may be the head of the screw itself, thescrew extending from the head or tongue Z7 through the plate Z6 intoengagement with the nut Z9. The gage L is used after the first groovehas been cut in alinement with the gage K and serves to locate thesecond cut exactly at right angles to the first eut for the reason thatthe edge of the gage L is set at right angles to the edge of the gage K,and the gage L is made to follow the vertex of the V-shaped groove rstcut inloeating the plate on the table for the second eut. In the samemanner the Vthird and fourth cuts may be squared or located exactly atright angles to the previous cuts by em- IIO adjusting the plate on twocutters and for this purpose is provided with grooves m and m',extending across the face of the disk, for the reception of the cutterslss riage bodily in its own plane, a table mounted O and O,respectively. The cutters are held in position by means of bevel-facedclamps P and P', the faces of the said clamps toward the cutter beingstraight, while their faces toward the opposite walls of the grooves arebeveled, as shown at p and p', to correspond tothe beveled walls of thegrooves. The clamping-pieces P and P are forced inwardly to clamp thecutters in position by means of set-screws Q Q', the threaded ends ofwhich engage threaded perforations in the clamping-pieces P P. Y

The plate with its grooves cut therein is denoted by R, its groove inone direction by r, and the groove at right angles thereto by r. Theparticular form of the groove which I prefer to cut is of a general Vshape in crosssection, with a steeper portion r2 at the upper portion ofthe wall adjacent to the central portion of the plate. groove is not,however, a matter of essential importance, as the cutters may beemployed to simply rabbet the edge of aplate or grooves of other formsin cross-section," as may be found desirable.

l. In a beveling-machine, the combination with a cutter-head and cutterscarriedthereby, of a carriage, means for moving the Vcaron the carriagein position to support the plate to be operated upon, means for movingthe table bodily forward and backward in a direction transverse to thatin which the carriage moves and means for raising and lowering the rearedge of the carriage beneath the cutters while the opposite edge retainsits position upon the carriage, substantially as set forth.
